What are the most important core components of smartphones? Of course it's that heart, the "phone chip"! For example, in the consumer group of young users, more demand may make the game smoother and more agile, and the mobile phone chip is the first demand. In the high-end consumer market, a good mobile phone chip has become the "standard", because this is the basis of fluency and endurance performance. To this end, the release of Qualcomm's new generation of Snapdragon 8 mobile platform has become the "white fumei" in the chip field, which has been sought after by major mobile phone manufacturers and consumers.
Throwing off the ARMV8 architecture used for 10 years, using the latest ARMV9 architecture, the new Cortex-x2 super core, the CPU performance has increased by 20%, the measured data of the GPU has increased by 52%, and while the performance has improved, the power consumption performance has also been affirmed by manufacturers and consumers. In addition, the new Snapdragon 8 also supports 5G millimeter wave, sub6 dual connection, and the downward peak reaches 10Gbps, which is not available in the competitor Tianji 9000. However, many consumers are attracted by the outstanding performance of the new Snapdragon 8, but ignore the hidden skill of this chip, that is, AI.
Some netizens said that "AI is not human-computer interaction, I usually rarely use ah." In fact, this is just a form of AI. The use of video to capture the subtle movements of the user's face for heart rate, blood oxygen detection, by identifying the voice to detect whether the user has asthma, depression and other diseases, so that mobile phone games support super resolution, improve the quality of photography, reduce mobile phone power consumption, etc., it can be said that the results of AI, and these AI functions, Qualcomm's new Snapdragon 8 have. Not only that, Qualcomm officials said that the seventh-generation AI engine integrated by the new Snapdragon 8 has improved by 4 times compared with the sixth generation in terms of performance.
How can Qualcomm achieve the ultimate in AI performance and use AI to empower photography and games? In fact, these results come from the Qualcomm AI Research Institute. According to public information, qualcomm AI research institute has a number of papers on AI published in arXiv, some of which involve the principle of combining AI with photography and games.
Take "taking pictures", the integration of the new generation of Spectra ISP and the new generation of AI engines has upgraded the face recognition capability of the new Snapdragon 8 from 115 points of the previous generation to 300 points, which has greatly improved the accuracy of the face recognition process, and the recognition speed has also been reduced from 24ms to 6ms, and the recognition speed has increased by 3 times, which has laid a solid foundation for mobile phone manufacturers to create more and more practical AI applications, so how did Qualcomm do it?
Among them, an article by qualcomm AI research institute mentioned that Qualcomm proposed a technology called "jump convolution", which subtracts two frames of images in the face recognition process and only convolves the changed part. In fact, this is to imitate the visual nerves of humans and frogs, and is very sensitive to dynamic target responses, which makes it easier for Snapdragon 8 to focus on the target object itself in the process of object detection, face and other image recognition, so as to release more capabilities to improve the accuracy and speed of recognition.
In the AI medical health convenience, in order to accurately determine whether the user has asthma, depression and other health problems, Qualcomm uses the AI on the side of the mobile phone and other terminals to propose a "federal learning" method, also known as "joint learning", that is, to ensure user privacy, data security in the case of data use and machine learning modeling, by analyzing the voice of mobile phone users, to determine whether the user has some health risks.
In addition, Qualcomm also joined forces with Google to carry Google's cloud neural search service (Vertex AI NAS), and the new Snapdragon 8 is also the first SOC to provide Google's cloud neural search service, so that developers can use cloud neural search service + AI to generate suitable models. For example, in the game, through dynamic compensation and interpolation algorithms, the game can achieve "super-resolution" display, and while the visual effect is improved, there will be no stuttering, power consumption spikes, and so on.
The continuous exploration and courage of unknown areas, the continuous attempts at architecture and new ideas, not only make Snapdragon 8 show higher performance and better experience, but also determine the new Snapdragon 8 chip in the industry's new height!
